The school says it's "continuing to take steps" to stop the bullying. But the first step it took was to tell Grayson last Thursday that he had to leave his pony gear at home because it's "a trigger for bullying."

Grayson's mom, Noreen Bruce, disagrees.

"Saying a lunchbox is a trigger for bullying, is like saying a short skirt is a trigger for rape. It's flawed logic, it doesn't make any sense," she told WLOS.

She's campaigning for punishment for Grayson's bullies, and for her son to be allowed to bring My Little Pony stuff to school again. And she's not alone. A Facebook page started by Grayson's friends caught the attention of the brony community, and he now has nearly 16,000 fans supporting him.
